Did your church leadership ever consider the Reformed Episcopal Church? I think they are to EPCUSA what PCA is to PCUSA: an evangelical alternative denomination.
rudy45 is correct. There are basically two most likely homes for an evangelical Anglican (American) church leaving ECUSA. The REC is one of those (and their coverage includes Texas, too). The other is affiliation with the AMiA, whose coverage also includes Texas. (Both groups are predominantly Eastern/Midwestern. Neither is well represented out here on the West coast.)

(It's "ECUSA" now, used to be "PECUSA.")

I am seeing a lot of alternatives for the disaffected of ECUSA. I would guess the direction that the Christian faithful wish to go in will depend on the orientation of their parish. If it was low church evangelical then those are good suggestions. But if they are more High Church of the Anglo-Catholic stripe then perhaps they should consider one of the continuing Anglican communions.

There are a lot. Take a look at the page in my tagline, you'll see them.
