There's nothing wrong with it, no.  In fact, doing a chroot install is one
of the alternative installation methods given in the alt-installation
methods documentation, and what I used to install Gentoo originally.  As
it happened, I was installing from a Mandrake for AMD64 system, but Gentoo
for AMD64 would work just the same, and since you already know Gentoo,
you'll even have  it easier than I did.

Gentoo Linux Alternative Installation Guide
Chapter 6, Installing Gentoo from an existing Linux distribution
http://www.gentoo.org/doc/en/altinstall.xml#doc_chap6

Actually, pretty much all it says is to use the existing installation to
partition the disk as appropriate (it gives a bunch of detailed
instructions for using parted, but use whatever you normally use, or
since it's a second disk, you don't even need to partition it if you
don't want to, tho I would, but that's me), and have the desired stage
tarball ready to go, then start with the regular handbook installation at
Preparing the Disks.

It does mention a special set of commands to use when you chroot, flushing
the environment so you don't contaminate your new one with variables out
of the old one.  Here's the sequence:

Code Listing 6.5: Flushing the environment during chroot
# env -i HOME=$HOME TERM=$TERM chroot /mnt/gentoo /bin/bash
# /usr/sbin/env-update
# source /etc/profile

... And the place in the handbook that you then start:

Gentoo Handbook, AMD64, Part 1, Installation
Chapter 4, Preparing the Disks
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=4

Then just follow the handbook...
