You're almost there. There are just two more changes required:
1) You've set beatLength to 1 8, so you also need to set beatGrouping
to ensure the beats are grouped in sets of two:
\set beatGrouping = #'(2 2)
2) The above still doesn't work with demisemiquavers, since there are
some default beaming rules which still need reverting.
Here are the default rules from scm/auto-beam.scm:
;; in 2 4 time:
;; use beatLength for all except 32nd notes
;; end beams with 32nd notes each 1 8 beat
((end 1 32 2 4) . ,(ly:make-moment 1 8))
((end 1 32 2 4) . ,(ly:make-moment 2 8))
((end 1 32 2 4) . ,(ly:make-moment 3 8))
The first and last rules here should be reverted (you can ignore the
second rule if you like; it matches the beat grouping you want, so can
be ignored):
#(revert-auto-beam-setting '(end 1 32 2 4) 1 8)
#(revert-auto-beam-setting '(end 1 32 2 4) 3 8)

It depends on your operating system. This page should narrow it down:
