1) Can a custom miniature with a blaster or a blaster and a melee weapon be used for a V-Set character with Melee Attack?
2) Can other characters of the same base size be substituted for newly "created" Rakghouls and Massassi Sith Mutants if a player does not have enough of these pieces?
3) Is there a link for rules about using customs?

Conversions
Conversions (customization of models) are allowed in SWMGPA-sanctioned Star Wars Miniatures tournaments, but must adhere to the following rules:
• The base of the conversion must be the same size as the mini being represented
• Base models must remain easily identifiable. A player must be able to tell what each model is on first glance at the battlefield.
• When a conversion is being used it must have the corresponding official card for each conversion model. For example, if a player is using three customized Mouse Droid models and one official Mouse Droid model in their squad they will need to have four official Mouse Droid cards.
• Additional equipment (including weaponry) may not be added to a model if that equipment is not represented on the model’s stat card. For example, a player may not add a blaster to a model that doesn’t have a ranged attack.
• Conversions maybe used instead of the recommended miniature as long as the official stat card or downloaded stat card accompanies it and it is easily recognizable as such miniature.
• For the purpose of counting as having a lightsaber refer to the stat card. If the card has the Lightsaber Special Ability, a Force Power with the word “lightsaber” or the card image itself depicts a lightsaber then the figure is considered to have a lightsaber. In the case of a minature (including Recommended miniature) having a lightsaber but not meeting the above criteria then it is not counted as having a lightsaber.
