It's probably possible but not very straightforward...
1. You need the Xorg-7.6.tcz for visual aspects (mouse and video integration)
2. When you click in VMWare Workstation "Install VMWare Tools" he will map the Linux tools iso (from your VMware installation) as a cdrom drive in the virtual machine. And then you will have to mount the drive yourself
$ sudo mkdir /mnt/temp
$ sudo mount /dev/sr0 /mnt/temp
3. Copy the installer to some place on a hard drive (because it is not small
, e.g.
$ sudo mkdir /mnt/sda1/temp/
$ sudo cp /mnt/temp/*.tar.gz /mnt/sda1/temp/
$ sudo umount /mnt/temp
4. Install extensions to build the tools. From what I remember, you will at least need
$ tce-load -wi compiletc perl5 linux-headers-$(uname -r) findutils
5. Put a marker to find the files the installer is creating anywhere, extract installer and run it
$ cd /mnt/sda1/temp/ && chown tc *.tar.gz
$ tar xzf *.tar.gz
$ cd vmware-tools-distrib
$ touch /tmp/beforeinstall
$ sudo ./vmware-install.pl
6. ...this is the moment where the real problems begin and you might encounter dependency or other problems...
(if however the installer ran correctly, then find the new installed files and pack them)
$ sudo find / -newer /tmp/beforeinstall -not -type d \( -wholename "/usr/*" -o -wholename "/var/*" -o -wholename "/etc/*" -o -wholename "/lib/*" \) > /tmp/list
$ tar -T /tmp/list -czvf /tmp/tools_install.tar.gz
out of this archive you can create your own extension mentioned in the wiki. The VirtualBox additions for the Open Source Edition are already available as extensions...
