Use GPO to set default language options, IME, display settings?

Question

new to GPO, we have a small Windows Server 2012 domain, all clients on Win7 or Win8.  All the clients require the following changes, anything I can automate this with GPO?  thanks
Under Control Panel\Clock, Language, and Region\Language > Add Traditional Chinese HK SAR
Under Control Panel\Clock, Language, and Region\Language > Traditional Chinese HK SAR > Options, Add Microsoft Quick IME
Under Control Panel\Clock, Language, and Region\Language\Advanced settings - change language bar hot keys
    - CTRL+SHIFT+0 ------  To English (United States) - US
    - CTRL+SHIFT+0 ------  To Chinese (Traditional, Taiwan) - Microsoft Quick IME
Under Control Panel > Region > Advimistrative > Change System Locale...  change to Chinese HK SAR for non-unicode programs
Control Panel\Appearance and Personalization\Display > Change the size of all items, use custom 123%.
Control Panel\Appearance and Personalization\Display > Update Text size to 8 for Title bars, Menu, Message Boxes, Icons, Tooltips
I found this for the display scaling registry changes but it is for 125% and it uses 78 for the dword value, not sure about custom 123%.

Hi lilyl,
According to your description, you would like to deploy some settings about language and display via GPO.
According to my knowledge, the steps you provided are from Windows 8 clients. Based on my test, you can use the following methods to realize:
Add Traditional Chinese HK SAR. Locate the registry key HKEY_CURRENT_USER\Keyboard Layout\Preload, and then add a String Value "next number"(which has not been used)=00000404.
The region settings. Please refer to the similar post:

The display settings. The post you provided tells us the related registry keys, and you should try to find the right value since you want to custom it.
In addtion, please refer to the following article to learn to deploy a registry item:
