I have not found nrf905 boards designed for 915mhz, other than $330 dev kit.
Looks like I will just go with the rfw69 which they are $5 915mhz boards available.

Although, there are only a couple of components that would need replacement you still have the antenna. The antenna on your module has probably been designed for 433MHz with a loop antenna as specified in the Product Specification. In order to operate the nRF905 at 915MHz you need a quarter monopole antenna, as described in our nWP-009 whitepaper. My recommendation would be to buy boards designed to operate at 915MHz

What kind of answer do you expect, basing on info "few" "different" components on "cheap board"? I would say it may work a bit worse. Assuming that "a bit" MAY also mean that range will drop to few centimeters.
