1 Change the shocks out (expensive)
2 Buy a lower seat (expensive and you suffer on long rides)
3 Build some height in your boots. A cobbler can add 3/4 of an inch of sole on BMW type boots and (or) you can buy oversized boots and add some inserts in them until the boot fits your foot well. This can add another half inch.
Lowering the bike with shorter shocks can render your center stand inoperable and make you afraid to use your side-stand on a windy day. Some people have had to spend 300 dollars to lower their stands.
The best advice I have is to buy a stock bike that fits you from the start.
