Not sure I can debug your setup from here, but if the question is about
getting eigrp adjacency to a BVI, it is possible.
I have the following setup
R5(E1/0)-------(E1/0)R1(E0/0)-------(E0/0)R6
R1 is configured thus:
interface Ethernet0/0
no ip address
bridge-group 1
!
interface Ethernet1/0
no ip address
bridge-group 1
!
interface BVI1
ip address 136.1.136.1 255.255.255.0
!
router eigrp 100
network 136.1.136.0 0.0.0.255
no auto-summary
!
bridge 1 protocol ieee
bridge 1 route ip
R5 and R6 have their ethernet's in 136.1.136.0 subnet and have eigrp
enabled on those interfaces.
Neighbors are as follows:
Router1#sho ip eigrp nei
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q
Seq
(sec) (ms) Cnt
Num
1 136.1.136.5 BV1 13 00:04:36 1 4500 0
3
0 136.1.136.6 BV1 11 00:18:57 92 552 0

Router5(config-router)#do sho ip eigrp nei

Your redistribution is probably not happening because the eigrp routes
are not getting there. I'd try simplifying your config first, then doing
a debug of ip eigrp and debug ip packet detail and look for retry
exceeds and unroutables to see why packest are not exchanged to form
neighbors.

Subject: BVI and routing...
Have a scenario where BVI is being used to connect to two EIGRP
neighbors and not getting desired results.

BB, R6 are in RIP; R1,R2,R3,R6 are in EIGRP AS
100
R6 has 3 subinterfaces for E0; E0.1 E0.2 E0.3. Created a BVI with
E0.1 and E0.2.
R6 cannot see R1 and R3 as EIGRP neighbors with BVI. R1 can ping BVI,
and R3. vice-versa. Have redistributed RIP to EIGRP on R6. The
Redistribution is not hapenning.
R6#sh ip eigrp nei
