Implement what some DSL access providers do. Unnumbered interfaces with /32 routing to the vlan. The last I checked, I think a J can even get the /32 route from radius when using autoconfig with radius auth. We did similar things with IPv6, as well. proxy-arp/proxy-nd to handle the cross talk.This is a very common problem for dedicated hosting providers (and why I give my dedicated hosts a vlan and a routed subnet, wasting IPv4.)
IOS 12.1 7206 confirmed. No autoconf, but static subinterfaces for each vlan (q-in-q supported or atm), unnumbered to loopback. DHCPv4 and static routing works. IPv6 had issues, but could handle static /64 per subint.
ASR/J MX, autoconfig w/ radius backend, manual subint/unit, or combination. DHCPv4 confirmed, static host routes confirmed. IPv6 not confirmed. Radius static host route establishment not confirmed. Still testing.
