Yes, i See no reason why this shouldnt work, even without Google services installed it should work (but notifcations dont work properly, for that you could consider Molly and their unifiedPush implementation)
Although I use Molly myself and it’s quite great, I never had issues with Signal’s notifications on GrapheneOS, LineageOS, or CalyxOS… Definitely stick with Molly, if you can!
