Hopefully the plan is to send both Yaako and Kochen on loan and promote Astralaga to 3rd GK when Pena leaves.
Players have strong say in this, and Yaakob only renewed with a promise of loan, and his agent is Zhavi whom we won't go against an agreed deal with him.
As you say, no Segunda team will promise him starting spot, and even if someone promise it, what prevents them from signing another GK the next week?
If he can't get minutes in newly promoted Andorra, at the age of 19, then that's his fault, not ours.
Same for Astralaga btw
