I think the times work such that you could do OTP-LHR-HEL-LHR-JFK-LAX-PHX-LAX-JFK-LHR-HEL-LHR-OTP for two extra legs. You'd arrive into PHX ate 23:00 and leave again at 06:00. I haven't confirmed this, but it might be possible.
If doing the HEL legs then you cannot do the LAX sector as well. It's a case of one or the other. I understand that you can combine, so do HEL out and LAX back but not both on the same routing.
Although, strictly speaking, you may be able to do both, but this takes it outside of the permitted mileage and could significantly bump the fare up. If it was allowed (at a decent price!) then I can assure you that more people would be doing this option. You don't choose to do a TP run and go direct from JFK to PHX when you can go via LAX on the transcon.
