Anytime soon. 

18 triads

015 017 019 035 037 039 215 217 219 235 237 
239 415 417 419 435 437 439

I am going to add digit 9 to each triad.

Adding only one digit to the list of triads gives me the same amount of plays as playing pick 3.  One chance in 10 on adding the correct digit. 

18 pick 4 plays

0915, 0917, 0919, 0935, 0937, 0939, 2915, 2917, 2919, 2935, 2937, 2939, 4915, 4917, 4919, 4935, 4937, 4939

Might even be a pick 3 winner in those triads.
