I want to add 2-meters capability to my Flex 1000..., but the DEMI 144-28 transverter is EXPENSIVE. I found a transverter board from the Ukraine http://transverters-store.com/144mhz.htm , also available on EBay, and was wondering if it could be made to work properly.

The Ukraine transverter will work.  I have the feeling that DEMI no longer excist. I ordered something more tha a year ago and did not even get a confirmation. Also no responds on e-mails's.

There was an article somewhere online that if you turn the power down these things are actually pretty clean, Of course then you need an amp which is just another way to dirty up the signal.

I agree you get what you pay for but i have been concidering one of these to play with a bit before steppping up to DEMI or Elecraft for my planned satellite station.

Mine works great on a 6300. Make sure that you get a large enough heat sink for the power FET. Look on Ebay for the heat sink.

Here is a link to the video.  https://www.youtube.com/watch?v=w8JQ0SIUlI8

I suspect they would be just fine for Sat work.  Maybe not so much for EME.

I have also heard of other whom had had orders in to DEMI for a year.

Now, will PowerSDR let me transmit at 32MHz, to create the entire IF range to cover all of 2 meters with this transverter? Or would it be difficult to hack the program?

It will not.  And modifying the source will not provide extended TX frequencies.  It is locked by a different mechanism.
