Want to create an iPad -centric live effects rig for flute, voice and maybe guitar

[JavaJ]

OK, now that I got my issues fixed from my previous posts- I am looking for some advise (hopefully someone has done what I am setting out to do).
I have 2 ipads (1 and 2) and an iphone 3GS. I have the iKlip Mini, iKlip iPad, iRig Mic, and was planning on getting the iRig or even iRig midi (maybe I will as I believe you can run the midi alongside the Mic/iRig).

Looking at using either IK's VocaLive or Amplitube for iPad. I am a good singer so I don't really need any vocal trainer/metronome, or event he voice cancel function- so that leaves me with just the stompboxes from VocaLive. I know I can purchase the 5 Vocal effects inside of Amplitube- but noticed that I would still be missing Reverb, Compressor and Parametric EQ- but gain a bunch of other stompboxes/cabinets/mics that are not part of Vocalive.

Would there be any reason that I a missing to not just centralize to Amplitube, but the VocaLive inapp option, and pickup the remaining 3 stompboxes to get the equivalent of both apps in one? Maybe someone from IK can chime in and offer advise.

My use will be purely for live use in a church setting- and I am all about doing stuff that no one has seen before- so Electic flute here I come!

p.s. would welcome other app suggestions as well. Don't want to miss out on a better app solution.

@JavaJ I think going the AmpliTube route with VocaLive in app purchases would be best. Especially since it is for flute and not as much singing. Plus with no need for the vocal tools, AmpliTube seems the way to go here.
