TrollCoinBot developer here (BitOBytes/Root, check my Twitter for verification). I'm not against the idea of adding more coins to TrollCoinBot - but the name is TrollCoinBot. Adding more coins wouldn't necessarily be difficult, just adding more daemons and changing some API calls internally as well as changing command syntax.

Realistically adding more coins to the bot would make tipping and other wallet-based functions a bit less trivial as you would need to specify which wallet you want to access at that point. (ex: !tip {user} {amount} {coin}, !tip @arkadeum 100 TROLL). With more coins comes more resource usage. You might not think a daemon costs a lot of resources but when you have users checking balances, tipping, betting etc multiple daemons can add up. Not to mention the disk space some coins take up now (sweet buttery Jesus BTC slow your roll!).

If Arkadeum is okay with adding more coins I'm just a code slave, I really enjoy programming. I'd say people would need to fund the server we would have to move the bot to however to manage multiple daemons.

Hopefully this information helps you guys. Keep sending suggestions - some of them are pretty tasty.
