Template port from rmg.txt

Hi! I have rmg.txt file with template preferences. How i can convert it to .json for vcmi? I’ve tried use H3 RMG Converter from mod list, but it does not works with my file.
May be someone can help me? Here is the file. It’s kind of Jebus Cross
rmg.txt (3.0 KB)

It’s hota template. There’s no converter for hota template format.
