Starting a new tank...

I currently have a freshwater tank which holds three Guppies. I was thinking, would it be at all possible to slowly converts it to a saltwater tank? I would slowly add the salt over several months, as to not kill the Guppies. Then when the tank had the correct salinity of a saltwater tank, I will remove the current sand and then add live sand and live rock. Is this even feasible? Would I need to buy a new filter and cycle it for saltwater or would my filter that is currently in the tank that was cycled in pure freshwater suffice? The tank is around 8 gallons. Here is the tank inhabitants I would like, obviously I can't have them all in my small tank. How many of them can I keep? How do I care for them?The inhabitants are in order with the inhibtants I want the most at the top of the list.

3x Guppies (Poecilia Reticulata)
2x Neon Blue Gobies (Elacatinus Oceanops)
1x Yellowhead Jawfish (Opistognathus Aurifrons)
2x Firefish (Nemateleotris magnifica)

2x Peppermint Shrimp (Lysmata wurdemanni)

6x Various Zoanthids (Zoantharia)
1x Green Star Polyp (Briareium sp)

Thanks in advance!

    IMHO m8, save up some serious cash, do some serious research on marine tanks,ie protein skimmers,wave makers etc, etc, and set up a really nice salty that you will really enjoy and have success with, they say that salt water tanks are an entirely different entity. To me, salt water tanks are way too hard, way to dear, not trying to dampen your spirits, just MY opinion, cheers :)

    I'm with Frayk, especially with a tiny tank like that you would struggle to maintain balance and it would end in disaster. When it comes to marine, the bigger the tank, the better. I also agree with the price tag concerns. If you want to do it properly, the initial cost is much higher than a freshwater and the tank itself requires more maintenance. All in all, it's a good idea but I wouldn't recommend it until you have done the research and can afford everything required.
