How to re-add removed packages

[Tz-Huan Huang <tzhuan@gmail.com>]

Hi,

I'd like to maintain some packages, which are removed in sid now.
(scim-hangul, scim-sunpinyin, scim-pinyin, scim-array).
How should I do? Should I send a WNPP bug report as a usual new
package, or just package it, change the maintainer to me and
upload it to mentors.debian.net to find a sponsor?
Thanks!

Tz-Huan
