Help me understand if I should do something different, please?

Hello I’m 40yo, living in the USA. I have about 85K in a Roth IRA (Vanguard Target Fund 2050). My current employer is now offering a 403b, with no matching (as they already contribute to a state pension). My wife is in the exact same situation, except she’s a couple of years younger, and makes about 68K/year (I make half of that, as I work part-time). I thought maybe using our 403b accounts to invest on Vanguard’s Target Fund 2055. Do you see anything wrong with that strategy? What else would the collective wisdom suggest? TIA
