Your employer is unlikey to even notice if your MCC was Prop/jet - and care even less.
That said - if you are going for a jet job with a sim check you will probably want to pay for some sim time first. Could work out cheaper just to do a jet based MCC rather than a prop based one and some entirely separate jet sim time.
Lowest cost to yourself whilst ensuring a successful outcome must be the best way to go.
Problem is - even after you are successful you don't know how much extra you did!
