Skinny Jenny Single pass carve speeds and feeds

I have some 1.75" thick mahogany that I want to carve a family crest. The piece will be approximately 14x20". I have had a good experience in the past roughing with a .25 flat endmill then finishing with a tapered ball mill, but curious if I could do a single pass with a skinny jenny for this piece using their recommended stepover and stepdown. This would save a lot of time if I could do one pass.

I have a stock journeyman x50 with the Makita router, so not at a spindle level yet, but just wondering if I could do a single pass, and if so what feeds/speeds I should use with a new bit. Is there a better strategy to do a 2D contour pass first and then do a single pass with the Jenny within that boundary?
