With all sympathy with you, let me directly answer your queries.
Answer: Yes, Police can file FIR if they believe the version of complainant but in SC/ST cases, it is not always easy to file a FIR as police also have to follow certain legal norms before filing FIR in SC/ST case.
Ans: You can go ahead with your planning as even in the worst scenario if FIR is filed you can go ahead and try to get FIR Quashed from Hon'ble High Court.
3) In case, FIR gets registered and your son's name also reflects in it then he would have to take anticipatory bail & he can go back to UK after taking court permission.
I have given answers very shortly. If you want to discuss it in detail the please contact me.
