Polaroid 600 film in an sx-70 and vice versa

Currently my Polaroid uses 600, it's an Impulse Portrait but at one time I had both Polaroid 1000 witch uses SX-70 film and I had a Polaroid Sun 600 LMS which uses 600. But  I never knew I could swap the film and because of that I had to stop using the pretty white one with the rainbow because I could only find the 600. now that I know this I want to get a nother Polaroid 1000 to play with.

My wish list...

We all have wants and wishes and I have many, like learning Italian and getting my Italian citizenship(working on that now) learning to play the guitar (also working on this one) I want my family and those I care about to have residue income. so that we can remain above the poverty line and not have to worry about the bills and such. and then I have all these things I want things like a Fiat 500 from the 70's and a Kleinlieferwagen (it's a VW postal truck that was used in northern Europe) I want a house for my family one that we can enjoy with room to do all the things we dream of doing and like to do. and I want cameras all kinds mostly large format film cameras and instant cameras like this Polaroid SX-70
