Firstly, unless you're tight for space, I'd not spend money on an MX240.
MX480 should be the bare minimum. Line cards are hungry for space.

We used to run single control planes in core switches, and have 2 core
switches per PoP. This was because those switches only handled Ethernet
traffic, no IP/MPLS.

I'd be hesitant to run any kind of routing device on a single control
plane unless it was designed as such. Then again, control planes are not
that much more expensive in current-generation core switches, so we are
now kitting them fully out from that perspective as well.
