Yes, the 'easy' replacement is to find another DPDT switch with 4 terminals that has jumpers (external or internal) such as what you currently have.
A six terminal DPDT will work fine though.
It would require you to make your own jumpers and as such, would not be the simple plug and play replacement mentioned above.
