I have microdontia, a slight overbite and a diastema (nearly 0.5cm). (photo)

A) Can I fix my diastema without touching anything else? Out of all these its only the diastema which bothers me. Otherwise my teeth are healthy. I am happy with my jaw structure, the overbite does not bother me at all. B) Also, would Invisalign do the job or would it need braces? C) IF braces are needed, how long does the whole process usually take? Awaiting any reply, thankyou in advance!
