Maintaining status after work permit expiry

[fq786]

Hello experts

I am on PGWP and my spouse on SOWP in Canada. Both our WPs are expiring in December this year 2023.
We are in the EE pool at a CRS score of 454. My score alone is 473. This is a pretty low score so i am not expecting an ITA before our WP expires.
Any suggestions on how can we maintain the status after our WP expires in December 2023?

Thanks all for your time
