Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I did, it seems to be a good idea but you'd have to be specific about at what standards they should be SRing for. And that they'd be OK with SRing a free-redis mon (considering the effort put in).
Hmmph you're right peope might not want to do it if it's going to be a full-redis. Maybe keep it inside the 4-5 people participating? I dunno. I just want to make use of those codes before they expire :/
Don't get me wrong, it's a really kind gesture but as mentioned above, it can be hard to find participants to do so. I think the products should still be free-redis but maybe you can throw in something else as well (maybe a top trader could put in a good SR as incentive)?
