I'm not sure if this is the intended method but you can do this by overriding the URL used for the AJAX query. This can be done by supplying plugin_options with a source option:

# Generate new look URL for channel mychannelname
lookup_url = '{}?myparam={}'.format(
  reverse('ajax_lookup', kwargs={'channel': 'mychannelname'}),
  param_value
)
# Instruct a field to use it
AutoCompleteSelectField('mychannelname', plugin_options={'source': lookup_url})

and then, in your lookup:

@register('mychannelname')
class MyLookup(LookupChannel):

    def get_query(self, q, request):
        optional_param = request.GET.get('myparam', None)
        if optional_param is not None:
            # do some extra filtering
