167 is PA-PAC-OPTIONS (MS-KILE 3.1.5.1).  Given Microsoft's history of
using types without registration, I would avoid anything in the 160-180
space as a practical matter.

I haven't heard of any conflicts with SPAKE being 151, so I think 152
should be safe.  But I would also be fine with picking a somewhat higher
base for registered but non-IETF-standardized types.
