Paul,
I’m a similar height to you, you can always use a Thompson, or other seta post with layback.
I’m ridng a short top tube Thorn Raven Tour which is designed for 26″ wheels and drop bars. (There is 55mm different in the top tubes-587 Frame size) I’m using straight bars with a 120mm stem with no problem.
I’ve looked around alot, Singular which make both drop and regular bar versions of 29ers only vary by 24mm (On the XL frames)in the top tube.
I’d say just go for it; play with stem, bars and seat post combinations, you’ll be fine. :-)
