I have a 6H6 in an RCA radio and I believe it is a dual diode. Would it be possible to replace it with two single 1n4007 DIODES?
The pin out for the diodes in the 6H6 is pin3 anode 2, and pin 4 is Kathode 2. Pin 5 is Anode 1 and pin 8 is Kathode 1.

The 6H6 is a low current diode that is usually used at RF or IF frequencies. It is used as a detector and AGC in an AM radio, and a discriminator in an FM radio. A 1N4007 has far too much capacitance to be used at these frequencies. If you wanted to replace this with a solid state device, I would look for a pair of germanium diodes like 1N34 or 1N60. If you can't find these you might try a 1N914 or 1N4148. These were meant for high frequency use. The tubes are available at any of the places that cater to old radio repair. So are the diodes.
You could make a socket adapter or replace the socket with a 7 pin miniature and use the much more easily available 6AL5 dual diode tube.
Or just buy a new 6H6 from AES or someplace similar. They are cheap, like less than $3.
