WI Catherine Cornaro Queen of Cyprus remarried?

In 1468 King James II the Bastard of Cyprus married by proxy the 14yo Catherine Cornaro in a final attempt to gain support from Venice...
They were married again in 1472 when she travelled to Cyprus...
A few months later he died mysteriously while Catherine was pregnant... She gaave birth to a son James III of Cyprus a few months later...
However he died too in 1474 aged 1 thus lefting Catherine as Queen Regnant of Cyprus...
In OTL Catherine never married again and Venice forced her to abdicate in 1489 in favor of the Republic of Venice...
WI Catherine Cornaro had married again? Maybe some French/Spanish Royalty and made him that way King of Cyprus?
How is that altering History? Could a marriage alliance with France or Spain (or any other foreign power) could have averted the Ottoman conquest 90 years later? Any thoughts?

(Based on an idea given by Dan1988)
 
Catherine Cornaro

Remember that Queen Charlotte, the sister of James II and his chief rival for the throne did not die until 1487, and had ceded her rights to the throne to the House of Savoy before then. If Catherine remarries, I don't think that it would have made any difference in the long run. The Venetian government actually feared this and finally got her out of Cyprus in 1489. A fairly remote possibility is Catherine remarrying, having issue, and then they marry a Lusignan. There were still a few around then.
 
A constant fight between Savoy and the potential offspring of Catherine Cornaro? Interesting...
But would this offspring and the subsequent alliance that comes with him can save Cyprus from Ottoman conquest?
 
Queen Catherine Cornaro

The kingdom was extremely weak by the 1480s. It had never recovered from the Mameluke invasion of 1426. Most of the local Greeks were rather apathetic about the struggles between the Roman Catholic rulers. I don't think that it could have survived much longer than it actually did.
