!
router ei 24098
 redist bgp route-map default-only
!
route-map default-only
 match ip add prefix default
 set tag 20
!
ip prefix default per 0.0.0.0/0
ip prefix default den 0.0.0.0/0 le 32

Nope, won't work. Redistribution, or 'route of last resort' check works by
walking through the RIB which is visible by 'show ip route' command. 
Adding a default with admin dstn set to 254 will make BGP default override
it, hence making BGP the default route. Redistribute BGP into EIGRP but
just match default route.
