Using a Roth IRA for high risk investing, thoughts?

Im 38 and have about $400k in my works 401k. I contribute 10% with a matching 5%. It’s mixed 60/40 between an sp500 index (large cap) and a dow total completion index (small caps). I recently opened a Roth IRA with about $25k in it and want to use it as high risk. Does it make sense to use this account solely for high risk value individual stocks I like and think will be good long term holds? I intend to max this Roth out yearly. Thanks for any advice.
