Alternative glyphs for a few characters e.g. lowercase a, lowercase g, lowercase k, digit 3 and 0

I love the existing glyphs in this typeface. (I don't think that the default glyphs of any of them is needed to be altered). But that said, I wish there could be alternative glyphs for a few characters, such as:

1. single-storey lowercase a - currently, only double-storey lowercase a is available
2. double-storey lowercase g - currently, only single-storey lowercase g is available
3. lowercase k with a loop (as in the italic lowercase k of IBM Plex Mono/Lilex) - currently, only non-looped lowercase k is available
4. digit 3 without serration - currently, only 3 with serration is available
5. dotted 0 and plain 0 (0 that looks similar to uppercase O) - currently, only slashed 0 is available

Again, I think that the default glyphs are already perfect, if these alternative glyphs does get created, they should be entirely optional.
