Sure, sounds good. I'll RNG a Japanese Emerald file for a Shiny Modest Mew in a few weeks; if you don't absolutely need the Kyogre to be from an English save file, I can get it from my Mew file.
I can do the Jolly Feraligatr :) Let me know of the set you'd like.
Shiny Feraligatr Lv 45
Jolly, Sheer Force
IVs: 31-31-31-X-31-31 (if also SpA is 31 is better)
EVs: 252 Atk, 4 Def, 252 Spe
Egg Move: Dragon Dance, Crunch, Aqua Jet, Ice Punch
Tutor Move: Super Power over Crunch
Is that ok?
