What risk? For the OP the FAA system provides easier, faster, and cheaper access to Part-FCL licences and ratings.
The UK conversion report does not presently provide a pathway from a UK NPPL(M) to a Part-FCL PPL(A) and furthermore the OP's SEP hours will not count towards the latter although they are creditable towards a NPPL(SSEA). Unfortunately the NPPL(SSEA), if granted on or after 8 April 2018, cannot be converted to a LAPL(A). See conversion allowances at

Any PPL(A) granted in accordance with ICAO Annex I is acceptable for commencing a Part-FCL CPL(A) modular training course and as both the US and Canada sensibly accept the OP's prior experience in credit towards their private pilot licences it makes perfectly good sense to use that path. Who knows, perhaps the OP fancies doing all this on floatplanes.
