Hi,
Although I'm not familiar with Unisyn, it does essentially what Sounddiver does. You should be able to use Unisyn I believe to do this. Since Unisyn and Digital Performer (DP) are made by the same company, you should be able to get all of the patch names in no problem. That is, of course, if Unisyn support the E4XT Ultra and EOS.
I don't know if Unisyn can generate OMS patch lists or not but on their website, they state that it provides seamless integration with DP.
HTH
