Is it important that everything has the same feel and matches for a wedding??

Buy the invitation sthat make you happy. This day is all about you, so thre aren't any rules you have to follow. The martini gles in the middle of the table would be cool, but turthfully no one will really pay close enough attention to the invitations to be looking for a theme. I think the laterns sound lovely. I promise that there will be no guest who whips your invitation out of their purse and begins comparing the color scheme with the pears on the table. It's not like a themed birthday party, so keep the pears if you like them, and get the invitations, and everything will be how you want. Congratulations on the engagement and good luck with the wedding!
