Royal plecos are quite rare and expensive. grab it while you can. clowns tend to be territorial like most plecos to other similar sized and shaped fish. galaxia pleco and peppermint are very nice attractions. most plecos are sy but get to know their surrounding after a couple of months and come out more imo 
all love their veg, e.g Zucchini
Yes. plecos will come out at night to feed of left over or any food. Royals can get to about 20"
Worth every penny thou.
haha
zebra plecos forever
Certain royals or 'panaques' are harder to obtain and rarer than others but the species the OP is probably able to get will be 190/191 which are very common and sell for very little nowadays. Although these with tollerate discus temps, it really is still a little on the warm side, the other factor would be diet.... discus as you know require a high protein based meat diet.... royals should be only fed it sparingly and as an occasional treat.... the main reason why i would say this isn't suitable for a discus setup. They also require wood within the tank and they make a huge amount of waste lol.
The L15 isn't a clown more often called candy stripe even though places still refer to them as clowns the species is different to what is traditionally know as a clown. L15 aren't overly aggressive but neither really are clowns (panaque maccus). This species wouldn't really be suitable for discus temps and there for wouldn't really be suitable long term
L30 is a lovely species, stays really small and would tollerate discus temps quite well... it should be fine with the food side of things but offering a varied diet is important as it is with all species of plec.
The galaxias, are we talking about L007?.... if so again we are struggling to keep it long term at discus temps, stunning fish that grows quite big, food again should be fine but varied veg matter should be offered just as much as meat alternative.
Really the only true suitable fish would be the L30.... theoretically all would work but they just wouldn't be in ideally conditions.
what plecos do you have??

correct. they tend to suck onto the discus and feed of their mucus on the skin Yuck!

Thanks for the great info! What one is the L30?
My discus tank is 27.5/28 degrees....rather than the hot side. I have wood and the base of the tank is heavily planted (good for the poop!) so does your points still stand?
For the most part yes it still stands... the temp is still above what most of the species listed should ideally be in, the L30 (peppermint) is the only fish listed which IMO should be kept long term at the temps you have mentioned. The royal would probably tollerate the temps but the dietary requirements of discus are completely different to a panaque (royal).... to much meaty/protein foods is very harmful and can lead to all sorts of health problems. The other 2 species just really shouldn't be at the temps mentioned.
I was thinking I could put the clown in with my other clown - are they likely to get on? I gather most plecos are solitary fish, so could they get aggressive?
The clown is a candy stripe
What is the main food source of Royals? Does that mean they would eat up a bit of algae? As that could be a blessing haha.
Short answer is wood.... yes they will much readily on veg and possibly algae but wood (softer the better) is the main dietary required food.
I had issues with my ottos sucking on my discus. But once i removed the offender, all is fine with the other ottos. Obviously dont want this problem with a pleco.
It doesnt happen as often as claimed, like ive said above, ive never known anybody having that problem.
Just now i have a tank with a pair of discus, a 6inch bristle nose and a clown (the one i talked about above). I'd like a royal, but i guess my 90L community tank is too small for him?!
Basically long term yes.... a smaller one will be fine for now but they do get big, albeit very slowly so if you plan on keeping long term then i would also plan upgrades as and when he/she gets bigger
