Why not...
work w/ just the base's plastic sub-plate, tape it down, then transfer punch the required new holes and bore new ones..
careful positioning is important ya know...
when you mount the base onto the table, leave the sub-base off...
remember not to orientate the sub-base in mirror image...
it's easy to do...
you should be looking at the bottom od the base plate as it lies on top of the table...
