How to use Reason effects in another DAW?

[tiger jackson]

Most recently I've been recording and doing mixing in Reaper, just more used to it for recording my Hardware synths. But I like Reason's Audiomatic Retro Transformer. I'd like to try applying that within Reaper, not sure how. I've used Rewire in the past for Reasons built in synths/drums.
I could just do the whole project within Reason but I haven't learned how to do any mixing & mastering within Reason... just much already used to doing it with Reaper.

Which version of Reason are you using? You options greatly differ if you've got access to the Reason Rack plugin or not.
