So I decided to go for 20m band. I had an option to set my VFO either
to 6mhz or 22mhz. I first went with 6mhz. But for my disappointment I
heard nothing but the band noise.

That frequency combination will work fine. I once homebrewed a 40
meter SSB rig using a 9 MHz crystal IF filter and a 2 MHz oscillator
and it worked fine. As a rule, the lower the oscillator frequency, the
more stable it will be. Your 6 MHz will be far more stable than 22
MHz.
