A look under the hood of the Vanguard 2035 fund shows a pretty standard Boglehead 4 fund portfolio.

It would not be hard to mimic and tweak with the NT funds you have in your 401K. But the issue with a custom portfolio is the likelihood that you would alter it based on short term volatility or not rebalance and over time you would under perform the simple target date fund.
But you could construct something similar with the NT S&P 500 fund, extended market fund, total international stock market fund, and the aggregate bond index. You'd only be missing a bit of international bond exposure. Not a big deal.
I'm quite fond of the TRowe price growth fund as well. I'd likely have some exposure to that, but overall I agree with
@GoldGloveschmidt. Simpler is better especially with your 401K. If you had a smaller Roth account separate from your 401K, maybe you could dink around, provided you have the right temperament and trust yourself during periods volatility or when perma bears like
@dscher burrow into your mind.
