That not exist...that will be an islamic nation with a local ruler and other.That's also a possibility. Just assume Malta becomes Islamic and hosts a Muslim equivalent of the Knights of St. John.
How to burn moneyAlso gives the Holy League yet another place to throw people and ships at in endless battles.
What would have happened if Malta fell to the Muslims? The course I am taking claims it would have disrupted Christian shipping across the Mediterranean and things would have gone haywire.
The knights probably re-locate to somewhere else, the Baleares maybe?
Menorca or Elba possibly.
Now I want a TL of Napoleon becoming grand master...
What is your PoD?
The siege of Malta (with hordes of Muslim soldiers against 600 Maltese knights) results in the fall of Malta before reinforcements arrive.

If the knights survive the siege... a pretty big if... then they're relocated. Spain may allow them to settle in Menorca to protect the Spanish Coast.
Malta becomes an Ottoman Base for raids on Italy and a base for Ottoman/Muslim Shipping. Possibly no kidnapping of Ibrahim I alleged son Sehzade Osman. If the butterflies allow Ibrahim to become Sultan. Depending on how strong the Ottoman Navy remains will also mean how long their rule on Malta will be. Also, some of the island population will be sold as slaves to North Africa.
To be fair, there's a fair bit of pressure taken off the Ottoman navy strategically if they have eliminated the main jumping off point for Western European freebooter activity into the Eastern Med. There's not really a force in the East capable of really threatening them, and the Spainish will be wary about gambling with a deep strike like Lepanto if a lose there would mean a weak Med fleet in the face of now much freer Barbarby Pirate and a strong Ottoman navy. I think this very well could butterfly away Spainish participation in the Holy League,and without them I don't think the Italians can easily save the Venetian position. That would go a long way towards tighter ties between North Africa and the Ottoman core territories
I don't know if it butterflies away Spanish participation in the Holy League. Spain had more religious regions to join, even without Malta being a Christian base. However, OTL Holy League is butterflied. No Italian power is willing to fight the Ottomans without strong Iberian backing. Venice will peace out sooner.
I do however think that Spain could start its own campaign, assuming the knights are in Menorca and settled long enough to have an own strong force again. If the Knights fall with Malta, Lala Kara Mustafa Pasha won't be kind to the Knights if we use his example in Cyprus against the Venetians. So the numbers of knights will be low and need new knights again. A future Spanish lead campaign may be in Algeria.
