Once I reach epic spellcaster, I want to create a spell or ritual that turns me into a dragon somehow. I have silver dragon blood pretty close to me in my lineage (my great-grandmother was a silver dragon), so I think it would be neat to make a spell that allows me to turn into a silver dragon, complete with abilities.
Thanks for the input!

If dragon is your goal, go Dragon Disciple! Once you reach Dragon Apothesis (and pick up the Half-Dragon template from it) you can use Polymorph Any Object to be permanently changed into a dragon (Same Kingdom (animal, +5), same class (Dragon, +2), and either Same or lower Int(+2) (pick age category based on your Int, and it's the same!), or same Size(+2) (pick age category based on size, and it's the same!). Also, the bonus spell slots from Dragon Disciple are one of the very few ways to get them, although it doesn't increase your caster level. However, that PrC should be saved until after you get caster level 20 (so you have your entire non-epic spell list).
As for a spell to turn you into a silver dragon, complete with abilities, Shapechange (at least, the version in the SRD) gives all Ex and Su abilities. You can do it at caster level 18 (you did say you had a sorceror base under the Archmage, and it's a 9th level spell) three (or more, depending on your Cha bonus... but it's a ninth level spell, so that would require a Cha score of at least 28....) times a day for three hours (180 minutes) a day, for a total of nine hours a day. At 20th, that jumps to six times a day for three hours, 20 minutes each time, or 20 hours a day.
For an epic spell, that's just a fairly straightforward application of the Transform seed - which is by default permanent. Assuming you want an Adult Silver dragon (pulling stats from the SRD), that's a creature with 22 HD (7 HD above 15, +14 DC), Size Huge (assuming you are Medium, that's two sizes larger than you, +6 DC to spellcraft), Type Dragon (different than yours, +5 DC), ten Ex and Su abilities (Cloudwalking, Alternate Form, Keen Senses, Blindsense, Spell Resistance, Immunities, Frightful Presence, Breath Weapon, Tail Sweep, Crush, +10 DC each, +100 DC) with a base DC of 21; DC =21+14+6+5+100=146, before mitigating factors. If you are okay with taking your sweet time about the transformation, you can drop it down as far as you like with just the extra time; +10 minutes to casting time (-20, casting time: 11 mintues), +63 days to casting time (-126, casting time: 63 days, 11 minutes) would bring the DC to 0.... and would (nominally) make the spell free to research, and essentially gaurunteed to cast (unless you get interrupted).
