Conjure Minor Elementals

As per the spell, it allows the caster to conjure 1 of the following: One CR 2 Elemental, two CR 1 Elementals, Four CR 1/2 Elementals, or Eight CR 1/4 Elementals.

As of the 5e Arcanis Campaign Setting (ACS) book, we have the stats for Elementals of CR 1/2 rating, and the SRD permits the use of Azers and Gargoyles (both which are CR 2). However, there are no CR 1/4 nor CR 1 of legal use in the SRD for Arcanis 5e.

I can imagine the CR 1/4 Elementals can be stated up using the CR 1/2 in 5e ACS and adjusting them accordingly. However, what about CR 1 Elementals? I ask for legal use in LA settings purposes.

Btw, here are the SRD stats for Azer and Gargoyle printed for 5e
