In your situation I'd skip the amps if you're mostly using headphones. If you're buying new and can return that's pretty safe, or even buying used you could resell and most likely not lose much.
One thing I'll add: you might want to try an Omicron in addition to whatever you choose. That pedal really shines at lower blend settings because it can be beefy as fuck. I use that quite a bit with a B7K's eq only and kind of prefer it to the B7's drive sound. It's just fuller and more authoritative across the fretboard to my ears.
