Rough estimation:

If you have the software to draw the layout ($10k-100k) and to
generate the gdsII file you pay

$1k per mask (say 8 masks $8k)
$1k per wafer (some hundred ics)

And you need a foundry, too. Difficult for these few wafers you
need.

For the small quantities initial cost is the  killer.
The very first ic will cost you a total of some $100k,
depending on the amount of work.
Forget it.

>Would it solve the Vbe matching problem, too?

If it's done right, yes.
