IPIP would also get the benefit of possibly routing EIGRP between IPIP mesh sites so that if one BGP route were to have catastrophic failure, another BGP announced route would already be announced and EIGRP would route to that end point.
This is a joke, correct?
You're proposing fixing broken routing using a non-standard protocol. IIRC EIGRP uses IP multicast for announcements (same as OSPF) so you'd need to run it over some sort of tunnel (gre) interface anyways.
Just use BGP with a private AS up to the edge Internet connected BGP nodes if you're building tunnels.
Tim Osburn and myself (and others) had proposed standards based way to move the IPIP tunnels to a redundant gateway design a few years back. It's not hard, but there is no movement from ARDC to actually move forward with it. I'd be happy with a study of proposed ideas, at least it's forward movement.
