Using a small valve combo as a preamp

An idea I've had for some time now but am unsure how effective it would be.

Would it be possible to plug your bass into a small 5 or so watt all valve guitar combo to get a 'proper' overdriven valve sound before taking a line out to your bass amp?

Or am I completely barking up the wrong tree?

* 5w valve combo > line level out > bass amp in or effects loop return

* No line out? 5w valve combo > spkr out > hughes and kettner red box (or similar) > line out to bass amp in or effects loop return (send H&K RB spkr out to speaker)

But probably easier to buy a dedicated valve pre-amp / distortion. Or something like a Tech 21 Leeds / SVT

This will drop the voltage to a level suitable for an instrument input:

Edit: You won't need a 50W resistor. 10W should cover the worst case.
