"It is not a bad idea, absolutely," Finch told cricket.com.au.
"The more time and effort that can be put into it (will be beneficial).
"I think with the T20 World Cup coming up it is going to be of extra importance.
"It is a trophy that has eluded us so far and we probably haven’t brought out the best in terms of making the semi-finals in the last couple of World T20s."
One-off or two-off T20Is have been added into series in the past, where Australia haven't had the chance to field a full-strength team due to the demands of the other formats taking precedent, in particular winning this year's 50-over World Cup.
But with more three-match T20s to be coming up in the coming months, both at home and abroad, Australia finally have an opportunity to shape and select a very strong team.
Finch has admitted he has found it difficult in the past to obtain a strong level of consistency with the players, but has remained positive this will change in the lead-up to next year's tournament.
"It is probably something that has been a bit tougher in the past to have continuity in the team for a long time because you are playing one game at the end of a Test series or one game at the end of a one-day series," Finch explained.
"When Pat Cummins has bowled the house down and he has played 10 Tests (it’s hard to select him) … Mitchell Starc is the same.
"We haven’t been able to have the consistency at selection so it is going to be nice over this next period to have some of that.
"We have got an idea of what a 20 or 22 player squad looks like, which we feel can take us forward.
"We feel as though we have got a decent balance of players in and around that group who we can move forward with in 21 games plus a World T20."
Before Finch ultimately takes up his role as Australia T20 skipper later this month, he has a Marsh Sheffield Shield game for Victoria against South Australia to look forward to, where he is coming off a very strong 188 unbeaten performance in his previous match-up against Queensland.
