Cutting and patching a composite is do-able, but it isn't that simple.
As Steve says, if you don't know what the seat is made of (both composite and matrix ) or how the layers were laid up, then there's a good chance the repair will separate. At the very least, you will need to feather the edges over at least one inch each side and use compatible resin.
So widening the seat 10mm in one area will take a repair at least three inches wide.
And if the repair is across where the seat flexes, then you would have to remove more material so the flex now occurs all in new or all in old material to be sure it won't break.
And the seat won't respond like it used to.
However it sounds as if your problem isn't necessarily the seat width but the seating position and the design of the 'ears' at the top. If you are deep chested or sit forward, then the seat top is often designed to dig in to the mid point of the ribs. You may need a seat that has a 'deeper' top or extended ears. Tillet do a set of rib protectors that fit to the seat and spread the load, they work quite well.
They can also help stop the driver moving around in the seat too.
