Multilayer RF Stack up

So I'm trying to route an RF device, but do the complexity of the device, I can't route the RF on a single layer. I know routing RF on separate layers will loose a little bit of performance, but at this point it's my only option. Will the following stack up minimize the lost?

RF SIGNAL
GND
SIG1
SIG2
GND
RF SIGNAL

Would it be better to go with an eight layer board?

Yes. The above approach is ok. Just take care that Sig1 and 2 are separated greater extent such that there is no or minimal cross talk.
