Perfect 60 Liter Tank?

[FreshwaterFish]

HI I have a 60 liter glass aquarium and at the moment have 4 male guppies and 2 male platies in there.  However I am thinking about changing it around so as to have:
- 4 / 5 Male Guppies
- 1 Male Platy
- 5 Tetras
- 1 Mollie / Other Center Piece Fish - Any ideas?
 
What do you think?  My main aim is to create a really healthy, colorful tank where all the fish are happy so would this be okay?  
 
Any other stocking recommendations?
 
What have you got in your 60Ls?  I want to create the 'perfect' tank ahaha

My tank is about 60 litres (17 gallons) and my stocking plan is 1 male platy, 5 female platies and 6 male guppies.  Though it may change depending on what platy fry I get!
 
My choice is based on water hardness, I have pretty hard water with a pH around 8.1 so livebearers are very tolerant of that.  If I had soft water my stocking would have been different, I would probably have looked at harlequin rasboras and neon tetras.
