There are several ways to complete the sentence so that the meaning stays the same:

• It would be a good idea for her to go ice-skiing this winter. (Formal)
• She'd have a blast ice-skiing this winter. (Informal)
• This winter, ice-skiing would be perfect for her. (Emphasis on the ideal timing)
• I think she should really consider ice-skiing this winter. (Suggests encouragement)
• Winter is the perfect time for her to hit the slopes! (More excited and specific)

The best option depends on the tone and context of the original sentence.
