So, after looking at it more in-depth, I've realized that integrating the two systems is not going to happen quickly, due mainly to the fact that I'm in the process of switching apartments and will be for the next week and a half.  While I'll still be working on it while I can as this is something I'm very much interested in doing, at this point I'd say just pick one system or the other rather than wait on this and potentially hold the game up far longer than necessary.<br/><br/>In terms of character ideas, I'm going back and forth between a synthesist summoner using the Unchained version and a druid of some variety, although I'm far from nailing anything down so that can be easily changed to fit the party composition.<br/><br/><blockquote><div><cite>Anime_Chaos wrote:</cite><blockquote><div><cite>Jermayan wrote:</cite> - Pingpong issue of a single swallow/escape check is still present</div></blockquote><br/>Isn't that countered by the cumulative penalty on a prey's struggle check?

Granted, the stacking penalty for failed escape attempts does quickly start to make that less and less of an issue as the rounds go by, but as written it only triggers if you fail an escape check<span style="font-style: italic">and</span>take digestion damage.
