Given the copyrights, while you may find something else that covers Greek with a similar appearance, it won't be Monaco (it's not legal to distribute a modified font using the same name). The existing font covers only the Latin and Cyrillic alphabets. In Unicode (UTF-8) Greek and Cyrillic have different values, though they have some similar appearance.

The basic Cyrillic alphabet is similar to the Greek.
The encoding of the Latin, Greek, and Cyrillic scripts
- Following on from point #4, any universal character encoding must distinguish Latin, Greek, and Cyrillic as scripts. If it does not do so, it would have insurmountable interoperability problems dealing with any of the huge amount of legacy data which already distinguished the scripts. Note that multiscript (partially) universal character encodings predating the Unicode Standard all did this. That includes IBM's registry of glyph identifiers, DEC's and Hewlett-Packard's listings of characters and glyphs, Xerox's XCCS character standard, WordPerfect's proprietary character sets, and Microsoft's and Apple's internal system of character identifications. The library community maintains the same script distinctions in its own data formats: MARC 21 (published by the Library of Congress) and UNIMARC (published by IFLA). Even the East Asian character encodings, as they developed, also distinguished Latin, Greek, and Cyrillic. See, for instance, JIS X 0208 itself, which separately encodes Greek and Cyrillic alphabets from ASCII Latin.

In principle, you should be able to make a modified font for your personal use by copying glyphs from the Cyrillic codepoints to the (similar) Greek ones.
