There's a Cisco paper showing how do do that for a 2800 series ISR.  (Actually I recall the white paper showed how to have an Etherchannel between the ISR and a switch, but it should work for two routers.)  One of my old posts either has the reference or the white paper as an attachment.

Hello

L3 etherchannel l3 switch/router
===========================
1) default physical interfaces (if possible)
2) apply "no switchport" to physical interfaces ( l3 switch only)
3)configure port-channel on physical interfaces
-- port-channel will be created automatically

4) config port-channel interface with ip address
5) enable physical interfaces "no shut"

conf t
default int ran fa0/0 -1

int ran fa0/0 -1
shut (if possible)
channel-group 1 mode xxx

int port-channel 1
no switchport (l3 switch only)
ip address xxxx yyyyy

int ran fa0/0 -1
no shut
