You won't be able to do much with ESRI:54044 since it is not supported by PROJ:

$ projinfo -o PROJ ESRI:54044
PROJ.4 string:
Error when exporting to PROJ string: Unsupported conversion method:
Hammer_Aitoff

The other missing ESRI codes are similar, see:
https://github.com/OSGeo/PROJ/blob/55b1832a277eb7c0ee15c89a87c7d33dcda1cf8a/scripts/build_esri_projection_mapping.py#L741-L776


If support for these projections is needed, it would need to be
implemented in PROJ. This is best done through sponsorship:
