There is no direct way. But you can use your Hilton/Marriott status and match to Wyndham, which gives you an automatic match to CET\Caesars Rewards as they have a partnership. Then utilizing CET to match to MLIFE which can you match directly to Hyatt, since they also have a partnership. MLIFE Gold and above gives you Hyatt Explorist. Important note, the CET to MLIFE match requires you to be in person to do the match, at an MLIFE property outside of Las Vegas. If you get Hyatt Explorist from the MLIFE match to get Explorist, you do get the annual 4 Club Lounge access awards.

This may not be a viable or feasible way for you due to your location, but figure I'd offer it as an option.
