If you create your own DTDs and you have borrowed, even heavily from these, yes, you would be able to distribute the DTDs. I think 67 of the elements from dtbook dtds came from HTML.
However, one should not claim that modified versions conform to DAISY or NISO. I have heard of companies who based a lot of internal work on the work DAISY and NISO did on these DTDs. I want to remphasise the Z39.98 Standard, which was designed for modification and extensibility.
