Why can't the L3 switches be run as L2 switches (ignoring the routing
capabilities) in that situation?  If those two switches were connected in
that case, then connected to the core, wouldn't that solve the problem of a
gateway being 3 or 4 L3 switches away?

Your gateway can't be any L3 switches (routers) away. It has to be on your
LAN. It has to be in your subnet. It has to be in your broadcast domain. It
has to be in your VLAN. For one thing, a host ARPs for its default gateway.
ARP uses broadcast.

I just noticed your comment and wanted to add my comment. Without being able
to decode your drawing, it's hard to tell exactly how to answer, but I'm
just trying to get you to think about what really happens to packets on a
campus network. The network design you're considering isn't just
impractical. It won't work, if I understand it correctly.
