Means to get to the LWM:

1) Dark Curse

2) Magic Beans (supposedly, Blue gave Bae the last Magic bean and said there were no more when Rumples begged her for one). Hook also had a magic bean which Rumples tried to acquire, but all Rumples got for his effort was Hook's severed hand.

3) Silver Slippers (Rumples had Jefferson search for them which I think he knew that Zelena had them)

4) Magic wardrobe (Blue had Geppetto carve one out of the last Mystic tree in EF. And these are only good for a few uses)

5) Time Portal Magic (which Emma convinced Rumples to take the forgetfulness potion instead of going back with her, Hook and Marian)

6) Shadow (I don't think Rumples was at the time prepare to take on Dad\Peter Pan to get the services of the shadow).

7) Pegasus sail (destroyed by Kalian just before becoming the pirate Hook)

So basically Rumples only had only the Dark Curse as the way to LWM...  Now it is certainly possible that the Snow Queen had a magic bean or access to some of the above or some other means... but I doubt that, just because Rumples would of connive\bargain with the Snow Queen out of them in the first place.
