I suppose it would be an interesting idea. I guess if you had the cash to spare a stiletto head and the time/expertise to convert it to use the 6L6. Anything's possible.
Maybe it would be a unique sound, like a recto with EL34's.
find a friend that has a dual rec. Use the Stilleto as strictly a preamp, and use the dual rec as nothing more than the power amp. That is as close as you are going to get I'm afraid.
GOod luck.
