I'm looking at the 16F1826 and at least the comparator should be
identical.   There's some nomenclature difference, but comparator 1 has the
same inputs and outputs.  Was there something specific which didn't work?

But...   The cost of a 16f18260I/P is $1.43/singles and $1.09/1000PCS.
The PIC16F627A-I/P is $1.63/singles and $1.44/1000PCS.

That's a lot of parts to pay for even a few hundred dollars worth of
software work.

It's hard to generalize on what pin count is cheapest, I will say that  18
pin parts seem to be less favored anymore, I think because surface mount
makes the pin count not so critical.  So you have some tiny parts with 6-8
pins, then it seems like you end up with 14 or 28 pin packages at the low
end.  So pretty much I'd select between those 3 pin counts.
