Hi, the .rpl is the Reaper equivalent of .fxb. So there's more than 1 preset in there. But why don't you download Reaper, install it, fully testdrive for 30 days (you may be surprised at what you find) and by this occasion load up the FX you'd like translated? Too much work? But it can be lotsa fun, just try it. :D Cheers, Raphael ;)
