Considering a Fic collaboration

I was beginning a story, maybe calling it total badflank or something similar. Pretty much a revenge story where the stallion or mare goes in total overbonk (look it up on youtube. Too lazy to put link...) after somepony/thing kills the heroes best friend. Small chance of a crossover. Criticize me! I need ideas and changes! I wanna know what you wanna see in this! And what you don't! Here! More of these! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
