I am not able to understand how your research has indicated that Basis is dying. If SAP is used, Basis would definitely be required, I expect.
If you find other areas of SAP more interesting or appealing, then you should look into them more in detail. I expect for a person who has been a DBA, you may look into BW, CRM, Netweaver, etc. Then you may see how you can acquire those skills and get into a job. Ideally if you can convince an employer to train and employ you, it would be good. Even if you start at a lower income, it would be good considering long term goals.
Hope this helps. All the best!!! I appreciate people looking for challenges and trying to improve !
