It would be wise to NOT use load-sharing (aka equalizer) resistors &

there will be no problem as long as they are of the same type number.

I think I am willing to try using them without caps and resistors.
I allready have 1KV 3 A HER308's. And I have a bunch of thermal
epoxy. I just might purchase some of these to make things easier.

The HER308 looks like a 1N5408 with a specified reverse recovery time. I
like specifications those FFPF04F150S damper diodes. Digi-Key has them
available in only large quantities (non-stocked) but Mouser shows them
in-stock in small lots. Not knowing the dielectric capability of the plastic
TO-220 case, I'd probably mount them (with heatsinks) to an insulating base.

i was trying to get an order together and ordered all parts from Digikey. I got into
discussion with support, and I said the catalog could be a lot smaller and easier
to hold if they listed stocked parts. From the very beginning I always had problems
with DigiKey with stocked parts. Ordered the diodes from Mouser. Nice that many companies
have no minimum orders. That was a big deal years ago.
