Modify Fonts from Envato Elements

Can I download subscription fonts and modify them a bit? For example, all your fonts support only Latin letters. I need to make an inscription in Cyrillic. Can I take the letters and correct them a little. For example, the Latin letter V, if turned over, turns into a Cyrillic Л. And from the letter P you can make a Cyrillic Ф. Can this be done under the license? This will only be done for one commercial project, the updated font itself will not be published anywhere
