Good idea. It is fine.
"MicaMold". the trade-name, capacitors are almost the worst such capacitors ever made,
rivaled in their "quality" only by "Black Beauties".
FYI, I recently restored a National NC-57 receiver which was full of those MicaMolds. Out of
some 20 MicaMold capacitors, I found only one which wasn't completely shorted, and that
one was too leaky to use.
The receiver works amazingly well with all of those replaced by modern 630 V jobs.
