Please support SVG titles (replacing h1, h2 headings with graphic titles)

Hi,

I'd like to replace big headings/titles with hand-lettered SVG titles on some pages. This way loading additional artistic fonts could be avoided and there would be more artistic freedom at the same time.

How could this be done? Could it be added as an additional option to the headline block in GenerateBlocks besides the div and paragraph option? I've found some info about accessibility here: https://stackoverflow.com/questions/65257333/svg-inside-h1-tag
