idea So going to rework Pokemon Emerald, ideas for gyms?

Hey Guys and Gals

So I have been having fun editing Pokemon Crystal (may post the link [albeit unfinished] if someone can tell me how to make an ips patch from it), but I have decided to move onto Emerald now. I am going to change each of the gyms and the Elite Four, as well as a lot of the trainers. I will also revamp the overworld (not necessarily a 386 hack but close enough), including changing map themes, changing weather effects and so on and so forth. I am presently looking for ideas for good challenging gyms? For reference, the starters are Numel, Wailmer and Cacnea. The overall aim of the hack is to make the game more challenging whilst also showcasing/upgrading some Pokemon (i.e. making Pinsir Dark/Fighting, Teddiursa/ring Ground/Normal, Pidgeot into pure flying)

So far, I have Roxanne's gym changed to an Ice Type gym, and will be looking to change the look of it too. If anyone can give any ideas, that would be great. Part of me is thinking of maybe having the latter gyms specialise in two types but I dunno right now.

I also wish to ask if there is a tool available to let me change the typing of a move? Also, is there a tool to change overworld sprites (i.e. may, brendan, mother etc...)

Thank you,

Robbie
