This would be a very costly exercise and cost thousands and the aircraft would have to return to the US more costs.
Considering the cheapest flight from Boston to London is $150 dollars one way better choice.
Better would be a flight into the Shengen area of the EU as once in then you can move around most EU countries with no checks
The question is what passport do you hold? as some parts of the old Yugoslavia are inside the EU. Serbia is not.
Passport and customs checks are no big deal in Europe, as we are used to international passengers,
US airport are a nightmare to transfer through in comparison, to be avoided if possible.
At London Heathrow, if transferring internationally no visa is required as passengers stay air side and
do not enter the country as long as you are booked to the destination. Bags moved automatically no need to collect.
In fact you would need more visas and check into more countries, on a private flight.
Best of luck but I think it is a no go.
PS Legally a British citizen does not need a passport to leave or return to the UK but does need to prove they are a citizen of which a passport is an acceptable document but any other proof acceptable to the emigration officer is OK. Just need a passport to get into the country you are going to.
