Replacing the texts is probably the easy part, it's the writing of pages upon pages of support convos that is probably the reason why they're not implemented (Or so I assume). Also I'm pretty sure you can see who supports with who in the battle prep screen. If you're part of the team working on this hack I'll gladly write up one to send as a sample to look over and see if my writing style matches up well enough with what was envisioned. Let me know if you are and I could get it done by the end of the week.
