1957/8 Westinghouse B&W TV Conversion to modern - should I do it?

[Catsmeow]

I have almost the same set, (same box, different controls) - called the "signet series by Westinghouse" - black and white as well. The condition of mine is not nearly this nice, the wood is slightly dented and scraped, and it's missing a knob, the speaker fabric is stained.
I was planning on the same thing, replacing it with a new screen.

I was told that this tv isn't particularly rare, and especially not because it's black and white.

Is everyone saying not to upcyle it just because his is in great condition?

I don't want to ruin something rare, but if it's nothing special I'd rather it live on and be useful!!
