Present etiquette

Dear Internets -

An etiquette question. If I've received a present from my company for the holidays that will be difficult to transport on a cross-country move, but is also in a theme of gifts that I expect might be well represented in my upcoming wedding, is it appropriate to bring it back to the store and exchange it for something smaller and easier to transport? Say, for instance, this?

Thanks for your advice!

Cheers,
