But Leon's idea is worth digging into further.

I'm not a very good sewing machine mechanic, but I don't think it's probable that you will find a motor that will fit that housing. Instead, I'd find a Japanese mid-century model that came with a 1.5 amp motor, or I'd find a 66 and change it to a 1.5 amp motor. Also if I remember correctly, some of the vintage Kenmores have the 1.5 amp motor.
With the 66 or Japanese machine, you can use an existing table. Not so on the kenmore.

I own, use a 15-91 daily and curious as to what projects your undertaking and what your expecting from the machine. Very rare in my opinion for the 15-91 to complain with what is thrown at it. If it fits under the pressure foot, the correct needle fitted with a well maintained/adjusted machine then it will sew what you want. Maybe you just need to make the jump to an industrial???
